Title: Transversal filter
Inventor: ITOU YUUICHIROU
IPC: H03H15/02
Filed: 1978-04-26
Abstract: PURPOSE:To reduce the ripple at passage band without increasing the number of steps of transfer electrodes, by increasing or decreasing the weight coefficient of positive and negative polarity of the transversal filter uniformly by DELTA. CONSTITUTION:In the filter driven with three phase, when the weight coefficient h of the sectioning ratio (1+h)/2:(1-h)/2 of the third phase electrode for the weight coefficient giving is positive, the ratio is increased uniformly by DELTA, and when negative, it is decreased uniformly by DELTA, so that (1+h+DELTA)/2:(1-h-DELTA)/2 is obtained. Thus, even with the same number of steps of the transfer electrodes, the frequency performance is flat for the pass band as shown in the solid lines. The weight coefficient h is designed by FIR, and the value of DELTA is within the range of 0.001<=DELTA/ hm<=0.004 to the maximum value of h, hm. Thus, the ripple of pass band can be reduced by only shifting the sectioning ratio to a given value, in conventional electrode sectioning filters.

IPC: B07C5/18
Filed: 1994-03-22
Abstract: PURPOSE:To obtain the readings of measurement of an article at high speed and high accuracy without being influenced by an unnecessary signal such as bed oscillation contained in a measurement signal. CONSTITUTION:A scale 1 outputs the mass of an article as a measurement signal S1, and at the same time, an acceleration sensor 10 outputs an acceleration signal S5 by detecting a bed oscillation. In addition, an (fc) variable digital filter 4a in a first stage outputs the approximate mass value of an article including a bed oscillation component to a multiplication means 11 as a correction factor S4, and the multiplication means 11 multiplies the acceleration signal S5 by the correction factor S4 to obtain a variation signal S6 which corresponds to the bed oscillation. A subtraction means 12 subtracts a variation signal S6 from the measurement signal S1 to exclude the bed oscillation component, and outputs the fc variable digital filter 4b in the second stage. Further, the (fc) variable digital filter 4b enhances the response by filtering a low frequency using a comparatively higher (fcde) when the signal is entered, and outputs an LPF output S9 which indicates a high accuracy mass value after the removal of an intrinsic oscillation noise by varying the low frequency to a lower (fc) gradually.

Title: Grafting robot
Inventor: MIZOTA MORIKAZU
IPC: A01G1/06
Filed: 1995-03-10
Abstract: PURPOSE: To provide a grafting robot having excellent handleability. CONSTITUTION: Since a hycopotyl raising plate 82 is installed at a position at which a cotyledon removing hand 77 of a stock seedling feeder 17 is brought into contact with a hycopotyl, even if a stock has somewhat inclination, the inclination of the stock is corrected by the hycopotyl raising plate 82 when the cotyledon removing hand 77 is raised. Consequently, gripping performances and cutting performances of the stock seedling can be improved. Similarly, the inclination of a soft seedling can be corrected by the hycopotyl raising plate 82. When a stock seedling is supplied to the feeder 17, since the hycopotyl raising plate 82 is hit to the stock seedling, insertion operation is facilitated. Consequently, a stock is cut at a set position and grafting performances between a stock seedling and a scion are improved.
